Controllable design of tunable nanostructures inside metal–organic frameworks

The controllable encapsulation of nanoentities (such as metal nanoparticles, quantum dots, polyoxometalates, organic and metallorganic molecules, biomacromolecules, and metal–organic polyhedra) into metal–organic frameworks (MOFs) to form composite materials has attracted significant resear ... mehr

Fe/ppm Cu nanoparticles as a recyclable catalyst for click reactions in water at room temperature

New iron-based nanoparticles doped with ppm levels of CuOAc are capable of catalyzing cycloadditions between alkynes and azides to afford triazole-containing products. These reactions take place in water at ambient temperatures, enabled by the presence of nanomicelles that function as a del ... mehr

Signal enhancement and low oxidation potential for miniaturized ECL biosensors via N-butyldiethanolamine

We present studies on ruthenium-based electrochemiluminescence (ECL) focusing on conditions supporting signal enhancement and low oxidation potentials. Low oxidation potentials (LOPs) are especially attractive for miniaturized ECL biosensors, as microfabricated electrodes tend to detach fro ... mehr

Sensors, Vol. 17, Pages 1177: Improving Video Segmentation by Fusing Depth Cues and the Visual Background Extractor (ViBe) Algorithm

Depth-sensing technology has led to broad applications of inexpensive depth cameras that can capture human motion and scenes in three-dimensional space. Background subtraction algorithms can be improved by fusing color and depth cues, thereby allowing many issues encountered in classical co ... mehr
